David Wood	607eb322a8	trait_sel: skip elaboration of sizedness supertrait ... As a performance optimization, skip elaborating the supertraits of `Sized`, and if a `MetaSized` obligation is being checked, then look for a `Sized` predicate in the parameter environment. This makes the `ParamEnv` smaller which should improve compiler performance as it avoids all the iteration over the larger `ParamEnv`.	2025-06-16 23:04:36 +00:00
David Wood	118d4e62c3	middle: print {Meta,Pointee}Sized in opaques ... When `sized_hierarchy` is enabled, rustc should print `MetaSized` or `PointeeSized` instead of `?Sized` in opaques.	2025-06-16 23:04:34 +00:00
